Finance Tans formation

UK based, with travel to client site

Permanent

I’m partnering with a leading consulting organisation to recruit an experienced One Stream Architect to join a growing UK practice.

With a strong pipeline of large-scale One Stream transformation programmes, this role offers the opportunity to work closely with senior finance stakeholders, shaping solution strategy and advising clients on complex finance and performance management challenges.

You’ll act as the bridge between finance and technology, helping clients define their transformation roadmaps and architect solutions that deliver meaningful business outcomes. Alongside leading One Stream solution design, you’ll work directly with senior finance stakeholders to challenge thinking, provide strategic guidance, and help organisations modernise their performance management capabilities.

This is an excellent opportunity for someone looking to combine deep One Stream expertise with broader finance transformation and advisory responsibilities.

• High-profile One Stream transformation programmes
• Strong focus on advisory, not just implementation
• Opportunity to influence the direction of a growing practice
• Small, specialist team with significant exposure and visibility
• Leadership responsibilities across both clients and project teams
• Direct engagement with CFOs, Finance Directors, and Finance Transformation leaders

• Deep One Stream architecture and solution design experience
• Strong understanding of Finance processes, particularly Group Consolidation and Financial Close
• Expertise as a Consolidation SME
• Broader knowledge across FP&A, Planning, Budgeting, Forecasting, and Reporting
• Experience leading enterprise-scale EPM or Finance Transformation programmes
• Strong stakeholder management and advisory skills
• Previous consulting or client-facing experience
• The ability to operate at Senior Manager level, influencing both clients and delivery teams
